Put simply, if high-intensity magnetic fields were dangerous no one would be getting MRIs. Theoretical and experimental studies indicate that MRI is not harmful as confirmed by the millions of scans safely performed in the last several decades.
High intensity PEMFs are routinely used in medical practice. This includes not only MRIs, but also repetitive transcranial magnetic stimulation [rTMS], various muscle stimulation systems, such as the Neocontrol and Neotonus, among many others. Many of these are FDA approved indicating that there is some degree of acceptance through the conventional medical system of their usefulness and safety.
There are dozens and dozens of PEMF devices on the market and they vary in intensity from very weak (measured in picoTesla) to very powerful (measured in gauss or Tesla), so the term “high intensity” is purely relative. There are 100 microTesla in 1 gauss. The earth’s magnetic field, for reference, is about a half a gauss, or 50 microTesla. An MRI machine is upwards of 40,000 gauss. The PEMF-120 produces a maximum of 1.5 Tesla, or 15,000 gauss.
No matter whether they are weak or strong, magnetic fields have to be used appropriately to avoid risk and provide the maximum benefit. Generally speaking, the more challenging the health issue, especially associated with high levels of pain, Dr. Pawluk often recommends higher intensity PEMF systems for faster, better, and longer-lasting results.
